PSP versions question. Pls help

Hi guys new member here. Recently was looking to buy a PSP but then someone just intro me to version 7.11 and version 8.63. anyone heard of these versions? wats the different btw these 2 and the 3.4 OEA. pls help enlighten me. Are they any good?

Version 7.11 and 8.63 are both fake; they don't exist. Whoever told you that they were is a moron and/or is messing with you.

3.40 OE-A is a version that allows you to play homebrew games, such as Emulators or user made programs. The official 3.40 and higher version do not have this privilege. If you want to play homebrew, try to get a 1.50 or one that already has 3.40 OE-A and save yourself the hassle of downgrading.
